Are sniffers completely off? Seen a few local Turbo Z's do it.

From my experience, tailpipe sniffers seem to be fairly accurate at WOT, when gas velocities are the highest. Trying to tune idle/cruise/light load though, they tend to read a little lean.
I was doing some pulls on a Dynojet last month, and the tailpipe readout on the dyno's software consistently read about 1-1.5 points leaner than my Haltech widebands mounted in the downpipes.
